You can adjust the slicer's length by modifying Z using its scaling function. I've found that 50mm, 100mm, 150mm, and 200mm are ideal sizes. The attached STL file is optimized for vertical printing. This approach allows for smooth prints without support material, but it may compromise structural integrity. To achieve stronger results, rotate the model by 90 degrees using a slicer, then print with support material in place.
